0031362: Inspectors - MessageView plugin for message alerts

- append new MessageView plugin to display content of Message_Report;

- correct DumpJson of TDataStd array attributes to print Lower/Upper values;
- correct remove level of Message_Report to store stop time during removing all levels;
- append DumpJson for TFunction, TPrsStd attributes;
- correct DumpJson of XCAFDoc tools due to simplify performance of it;
- move AttributeInfo functionality from XDEDRAW into a static public method of XCAFDoc to call it outside;
- remove obsolete pane classes in DFBrowser plugin, now we may use DumpJSon panel to visualize this content of attributes;
- add new property panel in DFBrowser (synchronized with the same in other plugins);
- add button to switch ON DumpJson in DFBrowser(OFF by default, for better performance), also there is a context menu item in tree view;
- rename in DFBrowser "Property Panel" into "Property Panel (custom)";
- implement ViewControl_ColorSeletor and setting color in TreeModel_ItemProperties. Use only for light in VInspector now;
- implement setting false for all created AIS_Shape presentation to don't modify source TopoDS_Shape;
- remove not use VInspector_CallBack. It's possible using Message_Report/MessageView to track commands way;
- remove History panel in VInspector as not used, MessageView will be better solution for this;
- implement item and actions in VInspector for setting Lights in the view.
